GSK778 抑制 BRD BD2,IC50 分别为 3950 nM (BRD2 BD2)、1210 nM (BRD3 BD2)、5843 nM (BRD4 BD2) 和 17451 nM (BRDT BD2)。 GSK778 (0.01-10 μM;72 小时) 抑制人原代 CD4+ T 细胞的增殖活性和效应细胞因子的产生,包括 IFNγ、IL-17A 和 IL-22。 GSK778 (0.001-10 μM;5 天) 对 MDA-453、MOLM-13、K562、MV4-11、THP-1 和 MDA-MB-231 细胞。 GSK778 (1000 nM;72 小时) 在 MV4-11、MOLM13、MDA-MB-231 和 MB453 细胞中抑制增殖,诱导细胞周期停滞和细胞凋亡。 GSK778 (1000 nM;12 天) 降低原代人 AML 细胞的克隆形成能力 Cell Proliferation Assay Cell Line: Human primary CD4+ T cell Concentration: 0.001, 0.01, 0.1, 1, 10 μM Incubation Time: 72 hoursResult: Inhibited the proliferative activity of the cells and the production of effector cytokines. Cell Viability Assay Cell Line: MDA-453, MOLM-13, K562, MV4-11, THP-1, and MDA-MB-231 cells Concentration: 0.001, 0.01, 0.1, 1, 10 μM Incubation Time: 5 days Result: Inhibited the growth and viability of human cancer cell lines. Apoptosis Analysis Cell Line: MV4-11, MOLM13, MDA-MB-231 and MB453 cells Concentration: 1000 nM Incubation Time: 72 hours Result: Inhibited cell proliferation and induced a cell cycle arrest and apoptosis. |
